Witr Prayer

Bukhari :: Book 2 :: Volume 16 :: Hadith 109

Narrated Anas bin Sirin:

I asked Ibn 'Umar, "What is your opinion about the two Rakat
before the Fajr (compulsory) prayer, as to prolonging the
recitation in them?" He said, "The Prophet (p.b.u.h) used to pray
at night two Rakat followed by two and so on, and end the prayer by
one Raka Witr. He used to offer two Rakat before the Fajr prayer
immediately after the Adhan." (Hammad, the sub-narrator said, "That
meant (that he prayed) quickly.)"
